 /**
  * A synchronous <code>BundleEvent</code> listener.
  * <code>SynchronousBundleListener</code> is a listener interface that may be
  * implemented by a bundle developer. When a <code>BundleEvent</code> is
  * fired, it is synchronously delivered to a
  * <code>SynchronousBundleListener</code>. The Framework may deliver
  * <code>BundleEvent</code> objects to a
  * <code>SynchronousBundleListener</code> out of order and may concurrently
  * call and/or reenter a <code>SynchronousBundleListener</code>.
  * <p>
  * A <code>SynchronousBundleListener</code> object is registered with the
  * Framework using the {@link BundleContext#addBundleListener} method.
  * <code>SynchronousBundleListener</code> objects are called with a
  * <code>BundleEvent</code> object when a bundle has been installed, resolved,
  * starting, started, stopping, stopped, updated, unresolved, or uninstalled.
  * <p>
  * Unlike normal <code>BundleListener</code> objects,
  * <code>SynchronousBundleListener</code>s are synchronously called during
  * bundle lifecycle processing. The bundle lifecycle processing will not proceed
  * until all <code>SynchronousBundleListener</code>s have completed.
  * <code>SynchronousBundleListener</code> objects will be called prior to
  * <code>BundleListener</code> objects.
  * <p>
  * <code>AdminPermission[bundle,LISTENER]</code> is required to add or remove
  * a <code>SynchronousBundleListener</code> object.
  *
  * @since 1.1
  * @see BundleEvent
  * @ThreadSafe
  * @version $Revision: 1.15 $
